Georges Valensi

Georges Valensi

:"Valensi" redirects here. For the guitarist of The Strokes, see Nick Valensi"Georges Valensi was a French telecommunications engineer who, in 1938, invented and patented a method of transmitting color images so that they could be received on both color and black & white television sets.

Rival colour television methods, which had been in development since the 1920s, were incompatible with monochrome televisions.

All current widely deployed colour television standards – NTSC, SÉCAM, PAL and today's digital standards – implement his idea of transmitting a signal composed of separate luminance and chrominance. Because his invention pre-dated the actual introduction of colour television by so long, his patent was exceptionally extended to 1971.
